Romans 11:11-31
11 I say then, they did not stumble so as to fall, did they? Far from it! But by their wrongdoing salvation has come to the Gentiles, to make them jealous.
12 Now if their wrongdoing proves to be riches for the world, and their failure, riches for the Gentiles, how much more will their fulfillment be!
13 But I am speaking to you who are Gentiles. Therefore insofar as I am an apostle of Gentiles, I magnify my ministry
14 if somehow I may move my own people to jealousy and save some of them.
15 For if their rejection proves to be the reconciliation of the world, what will their acceptance be but life from the dead?
16 If the first piece of dough is holy, the lump is also; and if the root is holy, the branches are as well.
17 But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree,
18 do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you.
19 You will say then, “Branches were broken off so that I might be grafted in.”
20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear;
21 for if God did not spare the natural branches, He will not spare you, either.
22 See then the kindness and severity of God: to those who fell, severity, but to you, God’s kindness, if you continue in His kindness; for otherwise you too will be cut off.
23 And they also, if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again.
24 For if you were cut off from what is by nature a wild olive tree, and contrary to nature were grafted into a cultivated olive tree, how much more will these who are the natural branches be grafted into their own olive tree?"
Isaiah 62:4
"4 It will no longer be said to you, "Forsaken," Nor to your land will it any longer be said, "Desolate "; But you will be called, "My delight is in her," And your land, "Married "; For the LORD delights in you, And to Him your land will be married."
